Java.lang.ArrayIndexOutOfBoundsException 0?

Jingang_Wang · March 4, 2013, 11:27am

Hi guys,

I am created indices in my data and began to make some queries on it. I
could get the hits number, but I can not get the search results. following
is my code in java.
Can anybody tell my what I have missed? Thanks.

Node node = nodeBuilder().clusterName("myelasticsearch").node();
Client client = node.client();
QueryBuilder qb = QueryBuilders
.boolQuery()
.should(termQuery("kba.body.cleansed","steve"))
.should(termQuery("kba.body.cleansed","ballmer"))
.should(termQuery("kba.body.cleansed","Gaylor"));
SearchResponse searchResponse = client.prepareSearch("test")
.setQuery(qb)
.execute()
.actionGet();
System.out.println("there are " + searchResponse.getHits().totalHits() +"
hits in this search");
SearchHits hits = searchResponse.getHits();
for (int i = 0; i < searchResponse.getHits().totalHits(); i++)
{
System.out.println(hits.getAt(i).getSource().get("doc_id"));
}

After I ran my code, it would output there are 2 hits in this search, but I
can not iterator the SearchHits, and the exception just like following:

Exception in thread "main" there are 2 hits in this search
java.lang.ArrayIndexOutOfBoundsException: 0

at
org.elasticsearch.search.internal.InternalSearchHits.getAt(InternalSearchHits.java:144)

Have a look here: https://github.com/elasticsearchfr/hands-on/blob/answers/src/test/java/org/elasticsearchfr/handson/ex2/SearchTest.java#L267

	for (SearchHit hit : searchResponse.getHits()) {
		// in hit.getSource(), you will be able to get your doc
	}

Note that you can't do a loop on totalHits as Elasticsearch will return by default the first ten hits.
So if you hit 1 000 000 docs, you can't iterate on 1 000 000 (and you probably don't want to do it).

Does it help?

Hi David,
Thanks so much for your reply. It really helps.
However, I have tried your means, it also could not iterate in the hits
results.

Yes, I have a running ES node, and I could conduct search using
Elasticsearch-Head-Master.
While when I run the code, I just get the number of hits and can not
iterate the hits to get details.
The code snippet I created Index: CreateIndex.java · GitHub
I used bulkRequest to create the index.
Thanks for your time.

I tried with a matchAll query on my indices and I can iterate over the 10 hits and get a field from each source.
I also tried a boolQuery with 3 should term clauses and that was fine also.

I can't help more here without reproducing your issue.

What does a single document look like?

Note that you can't do a loop on totalHits as Elasticsearch will return by default the first ten hits.
So if you hit 1 000 000 docs, you can't iterate on 1 000 000 (and you probably don't want to do it).

Does it help?

Hi David,

I found that the number of hits is 2 via
searchResponse.getHits().totalHits() method.
However, when I used the hit array, the array size is 0. It's so weird.

SearchHits hits = searchResponse.hits();
System.out.println(hits.getTotalHits()); //output is 2
SearchHit hit_array = hits.getHits();
System.out.println(hit_array.length); // output is 0

Just a side note, it is not clear how you did combine index and search.
If you have added the search code right immediately after the index
code, it may not work because you also have to issue a refresh request
to allow the index for reading the just indexed documents.

Hi Jörg,

I suspected that also but he said that he gets its documents from another node.
He added also that he can run search using head plugin.

So I think that documents already exist there.

Forget to mention, it is not easy to follow the setup without knowing
the index settings. Is it possible you have disabled fields like _all or

Just a side note, it is not clear how you did combine index and search.

If you have added the search code right immediately after the index code,
it may not work because you also have to issue a refresh request to allow
the index for reading the just indexed documents.

Yes, I have a running ES node, and I could conduct search using
Elasticsearch-Head-Master.
While when I run the code, I just get the number of hits and can not
iterate the hits to get details.
The code snippet I created Index: https://gist.github.com/**

I used bulkRequest to create the index.

I understand you just create documents, without using existing index
settings or mappings.

You have several misconceptions in your code:

you can not define field mappings in XContentBuilder. You must use the
mapping API. XContentBuilder is just for content, as the name states.
you use termQuery, in fact you are not looking for terms, but for
analyzed text. For this, use matchQuery instead.
you use long field names, with path like notation, also with index
type included which will not work. You should use short field names
("cleansed") in queries.
you do not start the node with start() and do not stop with stop() - I
don't know if you want to join a running cluster, or if you want a
standalone test cluster =

To recreate the issue, I have rewritten your code, also removed your
private class references, and made it runnable as a TestNG test.

The code is here: Java code example for bitwijg · GitHub

The output I get works as expected.

Sorry, my fault. I was sloppy in the index creation/deletion action.
Please use

client.admin().indices().create(new
CreateIndexRequest("mytest")).actionGet();

and

client.admin().indices().delete(new
DeleteIndexRequest("mytest")).actionGet();

that is, with ".actionGet()"

Your code runs here successfully.

I ever used ES 0.12 and now 0.90.
In my current machine, I run ES 0.90, I have not replace the old ES
version, but the ES instance in that machine is not initialized now.
would it be affected?
